• Covers 2002 Scotts Lawn Tractor models (L1642, L1742, L17.542, L2048, and L2548), including both gear-transmission and hydrostatic-drive configurations.
• Official John Deere technical manual (Publication TM1949, January 2002 edition).
• Features 42 specific fastener torque tables, 18 exploded-view diagrams for engine and transmission assemblies, and 4 detailed diagnostic flow charts.

Documented System Assemblies

This 334-page document acts as the primary factory reference for the engine and chassis-component service of the entire L-series lineup. Once your instant download completes, you'll have immediate access to a comprehensive breakdown of all major mechanical subsystems.

The internal engine repair chapters detail specialized tasks and specifications, covering piston, ring, and rod clearances, valve settings, and cylinder bore runouts for both single-cylinder and V-twin configurations. Coverage extends directly to the drivetrain, providing specific maintenance parameters for both the Dana 4360 gear transaxle and the Tuff Torq K46 hydrostatic unit. Additional sections clearly outline steering geometry, brake system service, and PTO drive mechanisms. Always verify you are using the correct lifting equipment and securing the chassis before diving into the heavy drivetrain or under-deck maintenance tasks outlined in these chapters.

Specification Highlights

Having the exact factory technical data takes the guesswork out of critical engine parameters and maintenance intervals. For example, the crankcase oil capacity is documented at 1.4 L (1.5 qt) for the L1742, while the heavier-duty L2048 and L2548 models require 1.9 L (2.0 qt) with the filter installed.

You'll find exact mechanical tolerances throughout the manual, such as the intake valve clearance of 0.08–0.13 mm (0.003–0.005 in.) for the 17 HP single-cylinder blocks, and crankshaft end play limits defined strictly between 0.05–0.58 mm (0.002–0.023 in.). When it's time for reassembly, the guide provides exact cylinder head bolt torque sequences, peaking at a final-stage pull of 24.9 N-m (220 lb-in.) for the V-twin models, ensuring absolute factory-spec precision on the shop floor.
